WE ARE FOCUS ON SAFETY AND SECURITY

Selection of Web Slings and Round Slings:

  • Always select the appropriate lifting devices for the planned transport

according to type, length and lifting method. The load has to be fixed safely and must not be subject to unintentional movements. Selectionof the wrong working load limit and/or lifting type can cause mechanical failure.

  • Web slings are inappropriate for sharp-edged loads (only with additional sharp edge protection or an suitable coating e.g. PU, of at least 5 mm strength), or in a temperature range from -40°C to +100°C (PESand PA) respectively -40°C to +80°C (PP) Web slings and roundslings must never be stressed exceeding their carrying capacity!

Procedures for initial use:

Before initial operation of the selected web sling, you have to check for its correct identification and dimensions.

Never use a product which is damaged r without appropriate markings.

Identification of web slings /

roundslings:

All safespan products carry the labels prescribed by DIN EN 1492-1 + 2. The label indicates:

  • WLL = Working Load Limit (in tons), load capacity concerning the type of lifting
  • Material: PES = Polyester, blue label
  • PA = Polyamide, green label
  • PP = Polypropylene, brown label
  • Effective length for use (in meters)
  • Year of production
  • Manufacturer identification DD
  • Traceability code
  • GS-sign and inspection authority
  • CE-sign
  • Identification of the valid standards

User Manual

for safespan web slings and roundslings

safespan web slings and roundslings are lifting devices according to BGR 500 (formerly UVV VBG  and meet all demands of DIN

  • safespan web sling suspensions
  • Custom-tailored lifting slings and

roundslings, e.g. made from Polyamide or Polypropylene

We specifically refer to the following rules and regulations as pertaining to

the technical specifications in:

  • DIN EN 1492-1 web slings made of chemical fibres
  • DIN EN 1492- 2 roundslings made of chemical fibres
  • BGR 500 use of lifting devices for lifting gear operations

  • Working load limit for normal lifting

types

Not all depicted lifting types are

appropriate for every type of lifting!

ß = inclination angle (angle between

vertical and web sling)

LA = lifting type factor (related to direct

working load limit)

Example: working load limit for direct

10 t (LA = 1)

Each shipment of safespan web slings

and roundslings is accompanied with

an explanation of conformity with the

EU machinery standard.

Transport of loads:

Always follow a good lifting practice: Plan the lifting procedure, the lifting procedure and the lowering procedure in advance.

  1. Preparations: Determine and double- check weight and centre of gravity.

Read the report papers and freight documents, pay attention to marked points for lifting and marked indications of weight. Otherwise measure the weight with a crane scale. It is NOT appropriate to just estimate the weight. Only after correct determination of the centre of gravity the crane hooks can be brought to a correct position!

  1. Inform the person operating the crane about the weight of the load.
  2. Bring the crane hook vertically above the centre of gravity of the load.
  3. Lift and fasten the load: Loads can skid or fall if they are tied down incorrectly. A falling load can cause serious injuries or death. Lift the load in a way that avoids the damage of both the load and the lifting devices.

 

The following has to be taken care of

to avoid twisting and turning over of a load:

  1. a) For single leg suspensions the point of lifting has to be vertically above

the centre of gravity of the load.

  1. b) For two-leg suspensions the points of lifting have to be even on both sides and above the centre of gravity of the load.
  2. c) For three and four leg suspensions the lifting points have to be even in one level around and above the centre of gravity. Pay attention to the inclination angle ß: The higher the inclination angle, the lower the working load limit. Inclination angles higher than 60° are not allowed.

d)Three and four leg suspensions, when loaded unevenly, must be treated like a two leg suspension depending on the highest angle of inclination concerning

the working load limit. When different inclination angles occur with two leg suspensions they have to be treated like single way suspensions. You have to expect uneven distribution of load whenever:

  • The load is non-flexible (e.g. concrete parts, cast parts, short roll/bundles etc.)
  • The position of the centre of gravity is unknown
  • The load is formed unevenly
  • Different angles of inclination occur Use only appropriate lifting points that are of appropriate dimensions.

Never grasp or reach for anything under lifting devices!

Web slings and roundslings have to be slung in a way that allows carrying loads over their complete width.

Short eyes must not be selected when using eye slings. An aperture angle of 20° must not be exceeded e.g. for lifting on a crane hook. For short eyes use reduction suspensions.

Aperture angles of more than 20° are not permitted!

Never put seams of the web slings near or into the range of the crane hook or other lifting devices under any circumstances.

Avoid any damage to the label.

When using more than one lifting device both lifting products have to consist of the same material (due to e.g. identical elongation values).

Attention! Lifting is forbidden for suspended loads!

Exceptions from this rule is lifting of:

  • Loads of large dimensions, if it can be ruled out that lifting devices can slip together or the dislocation of the load is not possible
  • Long, rod-shaped loads under traverses if the diagonal movement of the traverse is prevented and the load does not bend too much. This does not apply if the type of load or the surface of the load or the lifting type keeps the load or parts of the load from falling out.

For lifting choker loads only eye slings with reinforced eyes must be used.

Web slings with high traverse stability, e.g. with permanent coatings, can only be used for choker loads if they are equipped with metal fittings.

Working load limit for choker loads is 80% only!

When using safespan suspensions in a way that not all legs are necessary, attach the unused legs to the suspension head.

The working load limit is reduced corresponding to the number of legs used.

  1. Stay clear of load area immediately after lifting and leave any area of danger.
  2. Inform all persons involved in the lifting procedure. Warn uninvolved persons in the range of the transport and in the corresponding lowering

danger zone.

Warning: Persons in danger include all slingers and other persons staying in the transport area.

  1. Give unambiguous signals to the crane operator. Only one person should give signals.
  2. Trial-lift the load and check for the following:
  3. a) if the load is stuck or jammed
  4. b) if the load is well-balanced
  5. c) if all legs carry evenly
  6. Lower down lopsided loads and sling them correctly
  7. Transport the load by crane
  8. When transporting bulk loads or transport in windy conditions lead

the load using a guiding rope or lanyard. Keep out of the danger zone e.g. by walking next to driving cranes instead of walking in front of them.

  1. Lower the load following the instructions of the slinger.
  2. Secure the load against falling and breaking.
  3. Fasten the liftings to the suspension head.
  4. When lifting lifting devices make sure they do not get entangled with the load.

Important references for use

and warning hints:

  • Avoid any dragging or jerking
  • Never attempt to pull out the web sling or roundsling from under load
  • Avoid dragging the load over a textile lifting device; never drag web slings or round slings across floors or over rough surfaces
  • Never keep the load in the lifting device if any damage may result
  • Textile lifting devices can only be used for sharp edged loads or loads with rough surfaces if the areas in danger are protected. A sharp edge means that the radius of the edge r is smaller than the depth of the lifting

deviced. safespan coatings protect web slings and roundslings against sharp edges. We differentiate between DoLex web slings with a permanent coating and web slings and roundslings with movable DoLex profile hoses. DoLex

permanent coatings should only be used for loads that are unable to move

in the web sling. Thus no relative movements between coating and load can occur. Because of this they are inappropriate e.g. for turning procedures.

In these cases safepan hoses are favourable.

Warning: Sliding on sharp edges can destroy even Safespancoatings!

PVC-and PU-protective material orother equipment (e.g. impregnations)only protect against rough surfaces butnot against sharp edges!

  • Web slings and roundslings mustnot be knotted or be loaded whentwisted.
  • Roundslings must not be joined byknotting or interchoking.
  • Textile products have to be protectedagainst flying sparks resulting from cutting, grinding or welding.

Cleaning:

Web slings and roundslings have to be cleaned with clear water only without

using additional chemicals. Products which have become wet through use

or cleaning should be hung up for drying. Do not heat them or quick-dry them in any case.

Storage:

Before storing always examine web slings and roundslings for possible damage resulting from use. Do not store damaged lifting devices. When unused they should be stored on a shelf in a clean, dry, well-aired environment. They should be kept away from heating, chemicals, fluent gases, corroding surfaces, direct sunlight or other ultraviolet light source.

Use of safespan web slings

and roundslings in

connection with chemicals:

The materials that are used for the production of textile products (PES, PA,

  1. PP) differ concerning their physical characteristics (e.g. grip, stability and abrasion resistance) as well as in regard to different resistance against hemical influences.

Manual for safespan web

Polyester is more resistant against many acids whereas polyamide is more resistant against many alkaline solutions. Polypropylene is resistant against many acids as well as against many alkaline solutions. Warning! All materials can be destroyed or dramatically reduced in working load limit by chemicals depending on concentration, temperature and duration. Feel free to ask the manufacturer for advice regarding the use with chemicals. If web slings and round slings have been in contact with chemicals, immediately clean them with clear water or other appropriate means. Make sure to follow the rules of safety. Even seemingly harmless acid- or alkaline solutions can become concentrated enough to cause damage by evaporating!

Use in different temperature ranges:

safespan web slings and roundslings are suitable for use in the following temperature ranges:

Polyester / Polyamide: -40°C to +100°C

Polypropylene: -40°C to +80°C

Contact us for information as these temperature ranges may change in a chemical environment. In temperatures below 0°C only dry lifting products

must to be used.

 

Regular inspections:

According to BGR 500, an expert has to examine lifting devices at least once a year. Use our safespan inspection service! We examine your lifting devices either in the safespan test centre, at your enterprise, or directly on-site. Depending on the operational conditions of the lifting devices inspections in shorter intervals may be necessary. This applies to intensive use, frictional wear, corrosion, heat, and if experience indicates that a higher danger of damage is to be expected. Over the period of use, visual inspections carried out by the user can make sure that no damages occurs which

might endanger the continuous safe use. Visual inspections also apply for metal fittings, connectors and identification markers. In the following cases the lifting device has to be examined by an expert:

  • in case of doubt about the usability
  • if the identification (label or marker) has been lost
  • after damages or incidents that may reduce working load limit

 

Examples of defects and damages prohibiting any continuous safe usage are:

Abrasion of the surface, axial section or cross section, cuts or worn areas on edges, eyes or meshes, chemical influence, damaged or deformed metal fittings, cuts or worn areas on roundsling hoses, damaged protection hoses or

sharp edge protection pipes.

 

safespan repair service:

If your lifting devices are damaged they can be repaired by safespan spe-cialists. This helps to save your money. Never attempt to repair lifting devices

yourself!

Indications for Disposal:

Safespan web slings and roundslings must no longer be used in case of

  • damage to the woven edges or woven textile or large amount of broken threads; e.g. more than 10% of the total number concerning the most damaged cross-section
  • damage to suspending seams or reinforcements or the corresponding seams
  • damage to suspending yarn clutch (no repair possible)
  • deformation caused by heat (friction, radiation)
  • damage resulting from aggressive chemicals
  • deformation, tears, fractures and other damages on metal fittings
  • unreadable or lost identification markers

General indications of danger:

Lifting of loads using lifting devices endangers all personnel directly under loads or next to loads. As the manufacturer, we have to remind you that

residual dangers exist while operating lifting devices. This holds especially

true if the connection between lifting device and load is not safe or the load

swings after elevation and endangers the slingers. Falling loads do endanger

persons and goods.
